When the volcanic eruptions in the Siberian Traps occurred it triggered the Permian Extinction.

Over 80% of marine species went extinct. Over 70% of land species went extinct.

CO2 levels today are climbing to those levels.

The oil industry is funding fascism because they possess the best climate forecasters and know what's coming.

The only thing no-one knows absolutely nothing about regarding its climate impact are the #microplastics in the sky:

@HistoPol @petergleick

We may not have firm evidence of the consequences of environmental microplastics, but we do have ample evidence of the catastrophic effects of atmospheric particulates.

They trigger famines, little ice ages, and the end of civilizations.

I completely agree with your summary.

However, not being an environmental scientist and they stating that at this point cannot determine the direction in which this is going, I don't dare to contradict:

"But whether they would warm, or cool, the Earth is unknown...

What really gives me headaches:

"👉The murk of #anthropogenic #aerosols in the sky has, overall, had a dramatic cooling effect since the #IndustrialRevolution (without them, *global warming would be 30 to 50 per cent greater than it is today*)👈.
